OF KENILWORTH, ILLINOIS GLOBE-MOUNTING MEANS Application filed November 5, 1931, Serial No. 573,256. Renewed May 5, 1933.

The invention relates to improvements in" globe mounting means of the type in which a globe-carrying meridian 1s ad ustably engaged with a slide carried by a post which 5 rises, from a base. Heretofore, inorder to hold the meridian in adjusted position within the slide, it has been customary to provide said slide with a finger-actuated set screw, but it is the principal object of the present invention to provide an improved and simplified construction in which the upper end of the aforesaid post constitutes aset screw for the purpose in question, obviating the necessity of a separate part of this purpose.

A further object of the invention is to pro vide an exceptionally simple and inexpensive, yet a rigid and desirable base structurefor carrying the above-mentioned post.

To loosen or tighten the meridian within the slide and allow adjustment of said meridian, the latter and the globe are held in one hand and thevbaseis rotated with the other, causing the upper end ofthe post to thread into or out of engagement with said meridian as desired, and a still further object of the invention is to make unique provision whereby the post cannot be tightened in the slide with such force as to strip the screw threads of either the slide or post.

With the foregoing in View, the invent on resides in the novel subject matter here1n after described and claimed, description being accomplished by reference to the accompanying drawing. i Fig. l is a side elevation partly broken away and in section.

Fig. 2 is a view similar to Fig. 1, but looking in a different direction.

Fig.3 is a detail vertical sectional view through the slide and the upper end of the post, showing a portion of the meridian in elevation.

Fig. 4 is a detail sectional view on line 4.-& of Fig. 3.

Fig. 5 is a horizontal sectional view through the base structure as indicated by line 5-5 of Fig. 1.

A construction is illustrated which has proven to be of advantage from numerous 5- 'standpoints, and while said construction is through which a meridian 15 preferably followed, minor variations may be made within the scope of the invention as claimed. On the drawing, the numeral 6 denotes a flat sheet metal base plate of circular outline having its peripheral edge turned upwardly and inwardly to provide a. channel-shaped riin flange 7. A single length of rather stiff, yetresilient wire, is-bent to provide a split ring 8 which is einbracedvby and frictioiially engages the rim flange 7, an arm 9 projecting inwardly from one end of said split ring to the center of the base plate 6, and a' post 10 rising from the free end of said arm 9. The upper end of post '10 is provided with a screw thread 11 which is threaded into a vertical opening 12 in a slide 13, said slide being preferably in the form of a rectangular block. This slide is provided with an opening 14 passes slidably, said meridian carrying the conventional globe 16 which is rotatably mounted uponit by desired means 17. When the upper end of t is post 10 is tightened in the opening 12, it holds the meridian 15 adjusted with respect to the slide 13, but when the base is gripped in one hand and the globe and meridian held in the other, counter-clockwise rotation of said base will loosen the set screw formed by the upper end of the post 10, allowing sliding of the meridian 15 within the slide 13 to any desired position. When the required setting has been attained, clockwise rotation of the base 6 again tightens the upper end of the post 10 in the slide 13 and clamps the meridian 15 in said position.

Due to the connection between the post 10 and the baseplate 6, the latter may slip upon the split ring 8 if said plate be further rotated after the upper end of the post 10 has been tightened to a predetermined extent in the opening 12. There is thus no danger of stripping either the thread of said opening or said post. Upon rotation of the plate 6 in the opposite direction however, to release the post 10 from engagement with the meridian 15, the end 18 of the split ring 8 so tenaciously presses against the rim flange 8 that turning of the base plate 6 upon the split ring,

will not take place, insuring that said plate 1 and split ring shall rotate bodily to turn and release the post 10.

It will be seen from the foregoing that novel,inexpensive and advantageous provision has been made for mounting the globe and for permitting easy adjustment of the meridian 15. It will also be seen that unique provision has been made to prevent stripping of the screw threads, which is rather important, particularly when the globes are made in small sizes of light materials, to be handled more or less roughly by school children.

Viewed in a diiferent light, the parts 10, 9, 8, 7 and 6 constitute a set screw upwardly threaded, into the opening 12 and having a head atits lower end of a size and shape to alone constitute a base for the globe.

What is claimed is 1 A globe mounting comprising a globecarrying meridian, a slide through which said meridian passes, said slide having a threaded opening from its interior to its lower end, a base-spaced downwardly from said slide, and a post carried by and having a frictional engagement with said base, said post being threaded at its upper end into said opening, whereby said post constitutes a set screw which may be tightened by rotation of said base for securing said meridian in adjusted position in said slide.

2. In a globe mounting, a base plate having an upwardly and inwardly curved circular rim flange, a length of wire bent to form a transversely split substantially circular ring frictionally embraced by said rim flange, an arm extending inwardly from one end of said split ring and a post rising from the inner end of said arm, the upper end of said post being threaded, a slide, and a globecarrying meridian passing slidably through said slide, said slide having an opening into which said upper end of said post is thread ed, said post end constituting a set screw for holding said meridian in adjusted position.

3. A globe mounting comprising a globecarrying meridian, a slide through which said meridian passes, said slide having a threaded opening'from its interior to its lower end, a post whose upper end is threaded into said opening and forms aset screw for holding said meridian in adjusted position in said slide, a base at the lower end of said post, and connecting means between said base and said post for rotating the latter when the base is rotated, said connecting means embodying frictional post-driving means adapted to slip if the base be further rotated after rotation of said set screw is stopped by predetermined tightening thereof, said post-driving means having a portion for preventing slippage thereof upon retrograde turning of thebase to release said set screw.

4. A globe mounting comprising a globe carrying meridian, a slide through which said meridian passes, said slide having a threaded opening from its interior to its low er end, and a set screw threaded upwardly into said opening and adapted to abut said meridian, the lower end oi said set screw having a head alone constituting a supporting base for the globe.
